Application filed December 5, 1922. Serial No. 605,064.

To all whom it may concern:

Be it known that I, HENRY A. ALLWARDT, a citizen of the United States,residing at the city of Battle Creek, county of Calhoun, State ofMichigan, have invented certain new and useful Improvements in LiquidDispensin Devices, of which the followlng is a speci cation.

ThlS invention relates to improvements in liquid dispensing devices.

The main objects of the invention are:

First, to provide an improved dispensing faucet for soda fountains bymeans of which the carbonated water is delivered so as to retain a largepercentage of the gas.

Second, to provide an improved dispensing device for soda fountains "andthe like in which the syrup and the carbonated water are deliveredthrough a single nozzle and by means of a sin 1e operating lever.

Third, toprovi e an improved dispensing device in which the quantity ofsyrup may be accurately measured or gaged.

Fourth, to provide an im roved dispensing device in which the likel' 00dof leakage of the valve is minimized.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.-

I accomplish the objects of my invention following specification. Theinvention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisapplication, in which:

Fig. I is a side'elevation of my. improved dispensing device, the waterand syrup supply conduits bein partially broken away, the frame of theountain or other support being partially broken away and sectioned.

n the drawing similar reibrence characters refer to similar partsthroughout the several viewsand the sectional views are taken looking inthe direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents th casing or'body of a sodafountain, 2 a carbonated water supply pipe, and 3 a syrup supply pipe.The body of my improved fixture comprises a valve body 4 having adisside elevation looking" charge nozzle 5 and body member 6 in the Iform of a coupling to which the valve body 4 is secured, the member 6being provided with a coupling member 7 inserted through the support 1and secured thereto by clamping nut 8. The valve body 4. and the mem-.

ber 6 have a registering water inlet passage 9 and the syrup inletpassage 10 and syrup receptacle passage 11. The receptacle 12 consistsof a base section 50 and a cap section 51 threaded upon the basesection. A cup-shaped flexible diaphragm 52 having a rim 53 at its upperend is disposed with its'rim clamped between the sections of thereceptacle-see Fig. III. A disc 15- is $6- cured to the bottom of thediaphragm and has a stem 16 projecting upwardly into an adjustable stop17 threaded into the top section 14 of the receptacle. This stop limitsthe upward movement of the flexible diaphragm part, thereby regulatinthe capacity of the receptacle. A domeike water receptacle 18 is mountedupon the valve body 4. This valve body has oppositely facin valve seats19 and 20 with which the disk v yes 21 and. 22 respectively ooact.

nect the passages 9 and 24 and when ad- 'usted to another position asshown in Fig. l to connect the passage 24 with the passage 23, the firstposition being the receptacle filling position and the second thereceptacle discharging position.

The vent tube 26 projects upwardly within the receptacle to a pointadjacent the top thereof and is connected to the passage 27 which opensinto the valve seat 19. A vent discharge passage 28,-see Figs, IV and V,opens into the valve seat 19, wh le the valve 21 is provided with agroove-like P9 29, and is adapted to connect these passages 27 and 28when the valve is moved to a point intermediate its filling anddischarging positions so that the gas may be vented from the top of thereceptacle permitting the water to discharge wlth less agitation thanwould otherwise result.

The syrup control valve 22 is provlded with a groove-like port 30 whichis adapted to connect the syrup receptacle passage 11 with the dischargepassage 23 and with a second groove-like port 31 which is adapted toconnect the syrup inlet passage 10 with the receptacle passage 11.

I preferably providehard fiber facings or gaskets 32 between the valvesand thelr seats, the purpose bein to avoid the fric: tion of metal onmeta and also to effectively seal the joints. The valves are retained bythe caps 33 threaded upon the valve body, the short stems 34 of thevalves projecting through the capsto receive the arms 35 of the valvelever 36, the valve lever being shown by full lines in Fi I in its waterreceptacle filling position, w ich is also the syrup .dischargingposition, the closed position of the valve being indicated by dottedlines, which position, however, connects the passages 10 and 11 so thatthe syrup receptacle is filled.

In operating the device, when the handle is thrown from the dottedposition to the position shown in full line'sthe charge of syrup isdischarged and the charge of water allowed to enter the receptacle 18.The return movement of the valve first vents the receptacle, as stated,and then draws the water from the receptacle. This is found to result ina very superior beverage as it is delivered with a very large proportionof its gas.

taneously filled and discharged. However,

I prefer the arrangement shown and have, therefore, illustrated anddescribed it in detail.

In the modification shown in Fig. IX the parts are the same with theexception that the valve body 37 is adapted to receive the tapered plugvalve 38 and the member 6 is provided with awater valve 39 so that thewater may be drawn directly from the water supply passage, that is, itmay be drawn independently of the main valve ,which also controls thesyrup. In this modification the water receptacle passage 40 opens to thewater receptacle. The vent passage 41 is indicated by dotted lines, thevalve having the vent port 42 also being indicated by dotted lines.

The valve has a syrup port 43. The ort 44. is the water inlet port ofthe valve. he port 45 is the discharge port thereof which is adapted tobe brought into register with the discharge passage 46. This valve hasthe advantage of controlling both the syrup and the water and the valvelever 36 is manipulated in the same manner as described. The structureshown in Figs. I to VIII, however, is preferred in that the valveseffectively retain the liquid and at the same time are very simple toproduce and assemble arid durable in use.

I have not atempted to illustrate or describe certain other embodimentsor adaptations which I contemplate as I believe the disclosure made willenable those skilled in the art to which my invention relates to embodyor adapt the same as may be desired within the scope of the appendedclaims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
